The Hawaii State Department of Education (HIDOE) is taking another step to monitor and adjust classroom temperatures. In a partnership with the Hawaii Natural Energy Institute (HNEI), classroom temperatures and environmental data collected at public school campuses will be posted to a new website. Beginning this month, the HIDOE Thermal Comfort website will feature data from 37 schools with weather stations and 62 schools with indoor sensors that monitor classroom temperatures statewide.
Solar-powered weather stations mounted on these schools transmit data to a receiver in the school office, which is then posted to the new HIDOE Thermal Comfort website. Indoor classroom temperatures are monitored by the use of 737 data loggers that record the temperature and humidity every 30 minutes.
"The Thermal Comfort portal is an important tool we use for heat abatement decisions," said Dann Carlson, assistant superintendent, Office of School Facilities and Support Services. "The public now has the opportunity to view the environmental conditions we monitor when determining the best cooling method for a classroom."
Teachers and students will have the opportunity to use the posted data for class projects. Additionally, information on local microclimates – climates of small-scale areas – will be useful for sustainable design across Hawaii.
"The linkage to interior environmental conditions also offers the opportunity to further the understanding between environment and building performance," said Rick Rocheleau, HNEI director. "HNEI has been using the data to analyze performance of its net-zero classrooms on both Oahu and Kauai with the ultimate goal of encouraging sustainable design."
HIDOE has weather stations and classroom sensors at schools on Oahu, Maui, Kauai and the Big Island. In some cases, weather stations may be installed at specific schools when it is determined that microclimates caused by landforms, vegetation or urban development are creating distinct thermal conditions.

While thermal comfort depends on several factors, including air temperature, humidity and air velocity, the Department continues to abate heat through a combination of active and passive cooling strategies. The $100 million appropriated by the Hawaii State Legislature helped to cool down 1,190 classrooms to date, with contracts set for more than 1,300 classrooms. HIDOE's heat abatement efforts also consist of installing ceiling fans, using nighttime ventilation, painting roofs with heat-reflective coating and extending shade.
